there isn't really much of a tool to score it that good but will help. i just ordered an am opener for my sust from a google search. send me a private message & ill tell u the site. or if the administrator is kool w/ it ill mention it on this thread.

what i am using for now is a bic pen cap for leverage over the top & just pull it forward & it will snap. the broken glass i wouldn't be too concerned cause there cant be a piece that small to enter the pin when u extract.
